iratentect July 24, 1906.v

To all whom it may concern:

Be it known that I, OscAn JUNGGREN, a citizen of the United States, -residin at Schenectady, county of Schenectady, tate of New York, have invented certain new and useful Improvements in Elastic-Fluid .Tur

. bines, of whichthe following is a specifica tion.

v The present invention has -for its object to improve the construction of elastic-fiumi .tur-

mes. e

In'the accompanying drawings, which are illustrative ofthe invention, Figure 1 is a partial axial section of a multistage turbine.'l

made in segments and secured together. by` bolts 2. This casing is mounted upon a base.

3 or upon another section of the casing, de`

. pending upon the construction .of the tur.-

attached parts 'an bine. lOn the base is an internal shoulder 4, with which the ring 5 engages. The shaft of the machine in .the present instance is vertically disposed; but it can be arranged hori-l zontally under certainconditions, 1n which case suitablemeans `would be employed to' prevent the diaphragm from leaving its seat when the steam-,pressure is removed. The upper surfaceof the ring is finished, and en gagin therewith is a diaphra 6.. InI this case t. erentire wei h t'of the iaph'ragm and parts is supported bythe shoulder 4. The

steam-pressure on the Adiaphragm'will firmly'l The -rliapl1x`agm is composed-of a. central pcrtionVand an outer., ortion 8, the l two parts being separated by a; uid-carrying assage Q'and united by strong radial 'ribs 10.

seat it.

he under surfaceof thev diaphra is inished to receive the detachable sect10nalnoz-- zle 11. This nozzle may beexpanc'lingio'ri',

non-expanding in vcharacter and rearranged to convertl the pressure' of thernotive fluid intoV velocity; and ldischarge it against the wheelbuckets- 12. The buckets are arranged on the periphery of thewheel and are f grooves-,and rivets or bolts 1t secured thereto by shoulderslB, exrggln'g 'in the ringand attached' the rows of Wheel-buckets are intermediate buckets 15, carried by an overhanging shout der formed on the inside of the ring. Be-

. tween the base of the intermediate buckets and the shoulder is a tongue and groove to center the par-ts. Bolts 16 pass through the bucket-base into. the ring from the under side. The intermediate buckets may extend entirely around the wheel, as in the present illustration, or they may extend only parf tally around. This depends uponv which stage the. buckets are located in, the power of the machine, and other conditions that need notbe mentioned. v

With the arrangement shown in Fig. 1 the ring can only be removed by separating the parts of' the other cylindrical casing, whereas in Fig.` 3 it can be removed without so doing,

because the outside diameter of the ring is 'less than the inside diameter of the-casing. The ring is provided with, an internal groove,

into which the base oi the intermediate buckets snugly iits. Suitable radially-extending bolts clamp the intermediates to the ring.

Only one ring has been shown; but it is evi-v dent that it can be duplicated ad Zibttum.

In accordance with the provisions of the patent Statutes I have described the principle lof operation `of my invention, together with the apparatus 4which I now'believe to Y represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is only illustrative and that the invention can be carried out by other means. lWhat I claim as new, and desire to' secure by Letters Patent ci the United States, is-

- 1. In an elasticdluid turbine, the combination of a casing, a diaphragm for dividing it into Wheel-compartments, and a removable rin located inside of the casingwhich is separa le from and engagesthe diaphragm and maintains it in a definite position.

2. `In an elastic-fluid turbine, the combination of a casing, a diaphragm'for dividing it into wheel-compartments, Huid-discharging etween the casing into wheel-compartn1ents, and in.-
